CSS Issue

You just assited me with a mobile image sizing issue but I think I may have done something wrong when I added the CSS.

On my desktop site my bottom header/page hero is missing https://www.tryhypnosisnow.com/wp-content/uploads/2021/02/NYC-Hypnotherapy-for-weight-loss-stop-smopking-4-scaled.jpg

Notice the difference between these 2 screenshots.

This is all of my additional CSS

#mobile-header img { width: 100%; height: auto; }
h1.entry-title {
display: none;
}
@media (max-width: 768px) {
    .page-hero {
        background-image: url(https://www.tryhypnosisnow.com/wp-content/uploads/2020/04/Hypnosis-NYC-for-quit-smoking-weight-loss-anxiety-phobias-confidence.jpeg);
    }
}
@media (min-width: 769px) {
    .main-navigation li.search-item {
        display: none !important;
    }
}
#mobile-header .inside-navigation {
    display: flex;
    flex-wrap: wrap;
    justify-content: space-between;
}
.main-navigation .mobile-bar-items {
    order: 4;
}
input.ticket-selector-submit-btn {
background-color: #001de0!important; color: #fffff;
}
@media(max-width: 1024px) {
    .page-hero {
        display: none;
    }

        max-width: 150px;
    }

    }
}
